We are all in this together. After years of attempts to get Microsoft's plan, I came to the conclusion months ago that there is no plan. Why would there be? When and if MSN Premium is linked to a newer browser, Premium will be all new and we'll lose what we like about Premium email, etc. In the meantime, Microsoft can conclude reasonably from a business approach that the customer must be getting something worthwhile for his or her money, or the customer wouldn't keep coming back. I pay $50/yr in one payment in January. Someday, either Microsoft or I will quit.
But, I do like to see my email in the traditional screen. I've developed a work-around that works for me. I keep Edge and Outlook in my tray, and I have my msn email account in both Outlook and Premium. When I find an email that I want to read in either of the other two emails that I carry on Premium, I transfer the email in my msn email folder, go to Outlook and read it there. If there's a link in the email, the link works. The link would not work that is embedded in the email if I opened it in Premium. If I clicked that link, such as "Read More," Premium's IE would not be recognized because it no longer is supported, and the link would not open. You all know that, of course. I'm not satisfied, but old habits are hard to break. ... but, come next January I might quit, break my old habit and adjust to Outlook or Google, or ?
